To all whom it may concern:

Be it known that I, Fn-mz MAX BERBERICH, a citizen of the German Empire,residing at Kiel, Germany, have invented a certain new and usefulImprovement in Methods of Milking Cows, of which the following is afull, clear, and exact description, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing bad to the accompanying drawings, forming part of thisspecification, in which- Figure lis a view illustrating an apparatus forcarrying out my method, applied to a cow; and Fig. 2 is a verticalsectional view of one'form of teat cup that can be used with saidapparatus.

' This invention relates to a novel method of milking cows.

It is Well-known that the sucking of a calf is the most perfect. mannerof milking and produces a greater yield of milk than hand milking. Thisis due partly to the fact that by the exertion of the muscles of thesuckling calf light or weak currents of electricity are generated whichare trans- 'mitted to the cows udder and, milk glands so that the milkflows freely and more abundantly, and partly to the fact that the actionof the rough tongue of the calf on the teats on the cows udder massagessame and has a reflex action on the muscles of the cow which causes themilk to continue to flow freely. l

The object of my present invention is to provide a method of milkingcows that will produce practically the same elfect on a cow as thesucking of a calf.

Briefly described, my method consists in subjecting a cow to a slightelectric shock to cause the milk to flow freely, and pressing the teatson the cows udder so as to produce a reflex action on the muscles of thecow.

In Fig. 1 of the drawings I have illustratod one form of apparatus thatcan be employed for practicing my method, and referring to said fi ure,A designates tea-t I cups that are pre erably made of rubber amlavhichare connected to tubes 1 that lead to a pumping apparatus, not shown.The inside faces of the teat cups are roughened Speciflcation of LettersPatent.

' and milk veins.

ing of metal, such, for example, as tinfoil.

A wire 4 which leads from a battery 5 or any other suitable means forgenerating a current of electricity, is connected to the metal contact 3on the inside of each teat cup and 1 Patented Dec. 7, race.

the other wire 6, which leads from said battery, contacts with some partof the cows body so as to complete the circuit, and'thus cause anelectric current to pass through the milk veins and glands of the cow soas to cause the milk to flow freely. The protuberances or roughenedsurfaces on the interior-of the teat cu'ps press on the teats which Isaid cups surround when a vacuum is created in the tubes 1 and thusproduce a reflex action on the muscles of the cow which causes the milkto continue to flow freely. An preferred kind of teat cups can be usedan the conducting wires 4 and 6 can contact with various parts ofthecows body as, for example, the udder, escutcheon, back In practicingmy improved method I prcfer to use a verylight, simple, direct current,although in some instances an interrupted or alternating current may beadvantageously employed.

I prefer to subject the teats on the cows udder to a pressing andsucking action at the same time the cow is electrified but, if desired,-the cow can be electrified before the milking operation.

Various used for practicing my method so that I- do not wish 1t to beunderstood that m method is limited to any particular type 0 milkingmachine.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is:

1. A method of milking a cow which consists in subjecting the cow to aslight electric shock so as to cause the milk to flow freelyandsimultaneously pressingthe teats on the cows udder so as to produce areflex action on the muscles of the cow; substantially as described.

inds of milking machines can be 2. A. method of milking a. cow whichcon- Sists in subjecting the )W to a slight electric shock, andsubjectin the teats of the'ccws udder to a combine 5 action;substantially as described.

3. The herein-described method of milk- -ing a c0w,.Which consists inapplying teat cups to the teats of the'cows udder, creating suctionwithin said teat cups and simultanepressing and sucking signature in theously subjecting the cows udder to a slight 10 electric shock.

In testimony whereof I hereunto afiix my presence of two witnesses, thistenth day of November 1908.
